SAWYER COUNTY: Osprey Lake EWM Control


Sawyer County in cooperation with the Osprey Lake Property Owners Association (OLPOA) is sponsoring a project to control Eurasian Water Milfoil (EWM) in Osprey Lake and implement management actions in the approved Osprey Lake Aquatic Plant Management Plan. Project goals: 1) EWM control will take place on 12-16 acres of EWM in Osprey Lake. The goal of the treatment is to reduce EWM to less than 3 acres or 2.5% of the littoral zone; 2) The OLPOA will develop a Clean Boats, Clean Waters program at the boat landing on Osprey Lake. In addition to a CBCW program, the OLPOA will discuss increased enforcement issues at the landing with the LCO Wardens and the LCO Tribal Police; 3) Lake residents will be educated about the lake, EWM, and native plants during a lake excursion with the Sawyer County AIS Coordinator; 4) Volunteers will be trained using Citizen Lake Monitoring Network methods to monitor EWM within the lake. Surveys will be done once/month from June through September to monitor treated areas and to look for new EWM locations. Project deliverables include: 1) Enter CBCW and CLMN data into SWIMS; 2) Provide maps (including EWM beds) to the lake associations for management; 3) Results of pre and post monitoring surveys of EWM beds. Are control activities successful and how are native plants responding?; 4) Provide documentation that the above goals were completed. Specific conditions for this Project: 1) The WDNR will be provided electronic and hard copies of all data and or reports/plans generated as a result of this project (APM Plan); 2) Follow department protocol when conducting the pre and post monitoring; 3) Provide lake maps to the lakes coordinator and enter them into SWIMS; 4) Contact Erin McFarland (715-346-4978) and Laura Herman (715-365-8998) at UW-Extension to learn about the Clean Lakes/Clean Waters Program and AIS monitoring programs.
